GlobalWarming

GlobalWarming

Thereis a methodicalor scientific agreement that climate change ishappening, and that the main force of this change is none other thanhuman activities. Global warming is basically caused by the burningof fossil fuels, which in turn thrusts dangerous gases such as carbondioxide and methane into the atmosphere. The effects of globalwarming are not only the environmental but also weather patterns,which are either directly or indirectly caused by human secretions ofGreenhouse gases. Global warming is anticipated to have robust, vast,as well as overwhelming magnitudes for planet Erath.

Globalwarming is already here. This is according to many scientificresearches and reports. Global warming is causing the melting of icein the two ice caps as well as mountain glaciers [ CITATION Ali14 l 1033 ].Global warming will cause a rise in temperatures around the globe.According to scientific studies, over the last century, the averageworldwide temperature has risen upto 0.8 degrees Celsius[ CITATION Ali14 l 1033 ].This is specifically according to the World MeteorologicalOrganization (WMO) report [CITATION Jul14 l 1033 ].This report indicates thatmore organisms in the last ten years died due to increase in heatemission.The deaths amounted to over 2,000 percent. According toNational Oceanic and Atmospheric Administration (NOAA), since 1880,2013 and 2003 are seen to be the fourth warmest years worldwide.

In2014, a report by World Meteorological Organization indicated thatthe levels of ocean rise due to melting of ice. This report showedthat the rise in sea level augmented by 0.12 inches, annually onaverage globally [ CITATION Jul14 l 1033 ].This is nearly twice the average yearly rise of 1.6 mm in the 20thcentury. Due to this, melting polar ice in the Arctic as well asAntarctic area, combined with melting ice sheets as well as glaciersacross North and South America, Greenland, Asia as well as Europe,are anticipated to raise sea levels considerably. This means thatthere will not only be an increase in the number of people affectedby this global warming, but also aquatic animals as well as glaciers[ CITATION Ali14 l 1033 ].It is reported that if the global rise in sea level is not stoppedwith immediate effect, quite a number coastal regions, whereapproximately half of the people’s population inhabits, will beflooded. The acidification of the sea water is as well greatlyimpacted by global warming. This has an effect on marine organismssuch as corals, glaciers and oysters[ CITATION Ali14 l 1033 ].This is mostly caused by industrial revolution, which commenced inthe early 1700s. Since then, the oceans’ acidity has risen bynearly 25 percent. This is according to the report provided byEnvironmental protection agency (EPA). According to this report, ifthe contemporary trends of ocean acidification continue, marineorganisms such as coral reefs are anticipated to be scarce in regionswhere they are currentlywidespread[ CITATION Ali14 l 1033 ].

TheEarth’s ecosystems are neither spared from the harm caused byglobal warming. Quite a variety of animal and plant species havestarted to move their range from the equator towards the north polesor to higher altitudes due to high level of temperatures [ CITATION Ali14 l 1033 ].Therate at which various organisms migrate is slower than the speed ofclimate change. Due to this, quite a number of animals may find ithard to compete with the new climate regime and may be forced to die[ CITATION Ali14 l 1033 ].
